My 4 month old and I both got head colds starting Monday. Definitely not COVID. He is still a little congested in his nose, but he has a horrible cough. What can I do for him? I have a humidifier running. I use saline spray and the nose bulb sucker. I even gave him 2 rounds of Zarbees cough syrup today. He has no temperature today, but was around 99.1 the other two days. What else can I do? Should I call his pediatrician? He is exhausted and miserable.
